Defending champion Rory McIlroy is two shots behind leader Jordan Spieth after the first day of the Australian Open golf.

He is 2-under-par after hitting a round of 69.

All players will wear black armbands in the second round in tribute to Australian cricketer Phillip Hughes, who died two days after being hit by a ball.

McIlroy finished second at the DP World Tour Championship in Dubai at the weekend, narrowly missing out to Henrik Stenson.
